Abstract
An integrated circuit includes: a first path suitable for transferring an input signal from a first point to a second point; a second path suitable for transferring the input signal from the second point to a third point; a first phase comparator suitable for comparing an edge of the input signal at the first point with an edge of the input signal at the second point; and a second phase comparator suitable for comparing an edge of the input signal at the second point with an edge of the input signal at the third point, wherein the first path includes a first delay circuit whose delay value is adjusted based on a comparison result of the first phase comparator, and the second path includes a second delay circuit whose delay value is adjusted based on a comparison result of the second phase comparator.
